a compound is found to contain 31.1% sulfur and 68.9% chlorine determine the empirical formula for the sulfur and chlorine sampl
ollegr [7]

Answer:

Empirical formula = S₁Cl₂ = SCl₂

Explanation:

The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.

This compound contains 31.1% sulfur and 68.9% chlorine.

That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.

Convert the mass of each element to moles using the molar mass from the periodic table.

Moles of Sulfur = \frac{31.1}{32.065 } \\

= 0.9699

Moles of Chlorine= \frac{68.9}{35.453 } \\

= 1.9434

Divide each mole value by the smallest number of moles calculated.

Units of sulfur =  \frac{0.9699}{0.9699} \\

= 1

Units of Chlorine =  \frac{1.9434}{0.9699} \\

= 2

Empirical formula = S₁Cl₂ = SCl₂

When sugar crystals dissolve in water the level of water does not rise appreciably why?
Vlad [161]
Water molecules have space in between them. They are not packed tightly in liquid form. So the dissolved sugar molecules fill the intermolecular space in between the water molecules. This is why you cannot really see a rise in water level.

A catalyst decreases the activation energy of a particular exothermic reaction by 56 kJ/mol, to 35 kJ/mol. Assuming that the mec
-Dominant- [34]

Answer:

Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol

Explanation:

Activation energy decreases from = 56 kj/mol to 35 kj/mol

products = 78 KJ lower in energy than reactants

Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol

attached below are the sketches of approximate energy-level for both catalyzed and uncatalyzed reactions
